pvg 32 vaLve group with cLosed centre pvp(pvb with FLow controL spooL)

PVG 32 Proportional ValveTechnical InformationFunction

When the pump is started and the main spools in the individual basic modules (11) are in the neutral position, oil flows from the pump, through connection P, across the pressure adjustment spool (6) to tank. The oil flow led across the pressure adjustment spool determines the pump pressure (stand-by pressure).

When one or more of the main spools are actuated, the highest load pressure is fed through the shuttle valve circuit (10) to the spring chamber behind the pressure adjust-ment spool (6), and completely or partially closes the connection to tank.

Pump pressure is applied to the right-hand side of the pressure adjustment spool (6). The pressure relief valve (1) will open should the load pressure exceed the set value, diverting pump flow back to tank.

In a pressure-compensated basic module the compensator (14) maintains a constant pressure drop across the main spool – both when the load changes and when a module with a higher load pressure is actuated.

With a non pressure-compensated basic module incorporating a load drop check valve (18) in channel P, the check valve prevents return oil flow.The basic module can be supplied without the load drop check valve in channel P for functions with over-centre valves.

The shock valves PVLP (13) with fixed setting and the suction valves PVLA (17) on ports A and B are used for the protection of the individual working function against overload and/or cavitation.

An adjustable LS pressure limiting valve (12) can be built into the A and B ports of pressure-compensated basic modules to limit the pressure from the individual working functions.

The LS pressure limiting valves save energy compared with the shock valves PVLP:• With PVLP all the oil flow to the working function will be led across the combined

shock and suction valves to tank if the pressure exceeds the fixed setting.• With LS pressure limiting valves an oil flow of about 2 l/min [0.5 US gal/min] will be led

across the LS pressure limiting valve to tank if the pressure exceeds the valve setting.

In the closed centre version an orifice (5) and a plug (7) have been fitted instead of the plug (4). This means that the pressure adjustment spool (6) will only open to tank when the pressure in channel P exceeds the set value of the pressure relief valve (1).

In load sensing systems the load pressure is led to the pump regulator via the LS connec-tion (8).

In the neutral position the pump control sets the displacement so that leakage in the system is compensated for, to maintain the set stand-by pressure.When a main spool is actuated the pump regulator will adjust the displacement so that the set differential pressure between P and LS is maintained.

The pressure relief valve (1) in PVP should be set at a pressure of approx. 30 bar [435 psi] above maximum system pressure (set on the pump or external pressure relief valve).

pvpc,pLug For externaL piLot oiL suppLy

pvpc with check valve for open centre pvpPVPC with check valve is used in systems where it is necessary to operate the PVG 32 valve by means of the electrical remote control without pump flow.

When the external solenoid valve is opened, oil from the pressure side of the cylinder is fed via the PVPC through the pressure reducing valve to act as the pilot supply for the electrical actuators.

This means that a load can be lowered by means of the remote control lever withoutstarting the pump. The built-in check valve prevents the oil from flowing via the pressure adjustment spool to tank. With the pump functioning normally the external solenoid valve is closed to ensure that the load is not lowered due to the pilot supply oil flow requirement of approximately 1 l/min [0.25 US gal/min].

Please note:With closed centre PVP the external pilot oil supply can be connected to the pressure gauge connection without the use of a PVPC plug.

pvpc,pLug For externaL piLot oiL suppLy

pvpc without check valve for open or closed centre pvpPVPC without check valve is used in systems where it is necessary to supply the PVG 32 valve with oil from a manually operated emergency pump without directing oil flow to the pilot oil supply (oil consumption about 1 l/min)[0.25 US gal/min].

When the main pump is working nor-mally, the oil is directed through the PVPC plug via the pressure reduction valve to the electrical actuators.

When the main pump flow fails, the external shuttle valve ensures that the oil flow from the manually operated emergency pump is used to pilot open the over centre valve and lower the load. The load can only be lowered using the mechanical operating lever of the PVG 32 valve.

pvMr, Friction detentThe friction detent PVMR allows the directional spool to be held in any position, resulting in infinitely variable, reversible, pressure compensated flow. This can be sustained indefinitely with-out having to continue to hold the mechanical lever.

Please note:PVMR should only be used together with PVB basic modules with pressure compensator.

pvbs,Main spooLs For FLow controL (standard)

pvbs,Main spooLs For FLow controL (with Linear characteristic)

pvbs,Main spooLs For pressure controL

When using standard flow control spools, the pump pressure is determined by the highest load pressure. This is done either via the pressure adjustment spool in open centre PVP (fixed displacement pumps) or via the pump regulator (variable displacement pumps).

In this way the pump pressure will always correspond to the load pressure plus the stand-by pressure of the pressure adjustment spool or the pump regulator.This will normally give optimum and stable adjustment of the oil flow.

PVBS main spools with linear characteristic have less dead band than standard spools and a completely proportional ratio between control signal and oil flow in the range beyond the dead band. PVBS with linear characteristic must never be used together with PVEM electrical actuators. The interaction between the small dead band of the spools and the hysteresis of the PVEM actuator of 20% involves a risk of building up a LS pressure in neutral position.

In a few systems load sensing pump pressure may result in unstable adjust-ment of the oil flow and a tendency towards system hunting. This may be the case with working functions that have a large moment of inertia or over-centre valves. In such systems main spools for pressure control can be advantageous.

The spools are designed in such a way that the pump pressure is controlled by the spool travel. The main spool must be displaced until the pump pressure just exceeds the load pressure before the working function is applied. If the main spool is held in this position, the pump pressure will remain constant – even if the load pressure changes – giving a stable system.

The use of pressure control spools, however, also means that• the oil flow is load dependent• the dead band is load dependent• the pump pressure can exceed the load pressure by more than is usual.

Due to these factors it is recommended that pressure control spools are only used when it is known for certain that problems with stability will arise – or already have arisen.

PVPX is a solenoid LS unloading valve. PVPX is fitted into the pump side module enabling a connection to be made between the LS and the tank lines. Thus the LS signal can be relieved to tank by means of an electric signal.

For a PVP pump side module in open centre version the relief to tank of the LS signal means that the pressure in the system is reduced to the sum of the tank port pressure plus the neutral flow pressure for the pump side module.

For a PVP pump side module in closed centre version the relief to tank of the LS signalmeans that the pressure is reduced to the sum of the tank port pressure for the pump side module plus the stand-by pressure of the pump.

PVG 32 Proportional ValveTechnical InformationElectrical actuation

Function The philosophy of Sauer-Danfoss electro hydraulic actuation, type PVE, is integration of electronics, sensors and actuators into a single unit that interfaces directly to the proportional valve body.

closed loop controlAll the proportional actuators feature an integrated feedback transducer that measures spool movement in relation to the input signal, and by means of a solenoid valve bridge, controls the direction, velocity and position of the main spool of the valve. The integrated electronics compensate for flow forces on the spool, internal leakage, changes in oil viscosity, pilot pressure, etc. This results in lower hysteresis and better resolution. Furthermore the electronics enable built in safety like fault monitoring, directional indication and LED light indication.

principleIn principle the input signal (set-point signal) determines the level of pilot pressure which moves the main spool. The position of the main spool is sensed in the LVDT transducer which generates an electric feed-back signal registered by the electronics. The variation between the set-point signal and feed-back signal actuates the solenoid valves. The solenoid valves are actuated so that hydraulic pilot pressure drives the main spool into the correct position.

inductive transducer, Lvdt(Linear Variable Differential Transformer). When the main spool is moved, a voltage is in-duced proportional to the spool position. The use of LVDT gives contact-free monitoring of the main spool position. This means an extra-long working life and no limitation as regards the type of hydraulic fluid used. In addition, LVDT gives a precise position signal of high resolution.

integrated pulse width modulationPositioning of the main spool in PVEA/PVEH/PVES is based on the pulse width modulation principle. As soon as the main spool reaches the required position, modulation stops and the spool is locked in position.

With electrical ON/OFF actuation the main spool is moved from neutral to maximum stroke when power is connected.

A fault monitoring system is provided in all PVEA, PVEH and PVES modules. The system is available in two versions: • The active fault monitoring type, which provides a warning signal, deactivates the solenoid valves and drives the spool in neutral. • The passive fault monitoring type, which provides a warning signal only. Both active and passive fault monitoring systems are triggered by three main events:

1. input signal monitoring The input signal voltage is continuously monitored. The permissible range is between

15% and 85% of the supply voltage. Outside this range the section will switch into an active error state.

2. transducer supervision If one of the wires to the LVDT sensor is broken or short-circuited, the section will

switch into an active error state.

3. supervision of the closed loop The actual position must always correspond to the demanded position (input signal).

If the actual spool position is further than the demanded spool position (>12%, PVEA: >25%), the system detects an error and will switch into an active error state. On the other hand, a situation where the actual position is closer to neutral than that demanded will not cause an error state. This situation is considered “in control”.

When an active error state occurs, the fault monitoring logic will be triggered:

active fault monitoring• A delay of 500 ms (PVEA: 750 ms) before anything happens.• The solenoid valve bridge will be disabled and all solenoid valves will be released.• An alarm signal is sent out through the appropriate pin connection.• This state is memorized and continues until the system is actively reset (by turning off

the supply voltage).

passive fault monitoring • A delay of 250 ms (PVEA: 750 ms) before anything happens. • The solenoid valve bridge will not be disabled but still control the main spool position.• An alarm signal is sent out through the appropriate pin connection.• This state is not memorized. When the erroneous state disappears, the alarm signal

will turn to passive again. However, the signal will always be active for a minimum of 100 ms when triggered.

To prevent the electronics from going into an undefined state, a general supervision of the power supply and the internal clock frequency is made. This function applies to PVEA, PVEH and PVES - and will not activate fault monitoring:

1. high supply voltage The solenoid valves are disabled when the supply voltage exceeds 36 V, and the main

spool will return/stay in neutral.

2. Low supply voltage: The solenoid valves are disabled when the supply voltage falls below 8.5 V, and the

main spool will return/stay in neutral.

Wwarning

It’s up to the customer to decide on the required degree of safety for the system (see PVE series 4 catalogue DKMH.PK.570.A1.02, page 19).

Note:1. Different degrees of safety are described on pages 56 to 59. 2. The fault monitoring does not work if the supply voltage to PVEA/PVEH/PVES is cut off – for example by a neutral position switch (see page 56). 3. When using PVEA/PVEH/PVES with passive fault monitoring it’s up to the customer to decide on the required degree of safety for the system (see page 56).

Please note:The letters AA, A, B, etc. denote spool types, see pages 62 to 69. The characteristic below is shown for spool travel in both directions. All other characteristics are shown for spool travel in one direction only.

pressure-compensated pvb, open or closed centre pvpThe oil flow is dependent on the supplied pump oil flow. The characteristics are plotted for a pump oil flow, QP, corresponding to the rated max. spool oil flow, QN. Increasing the pump oil flow to 1,4 × QN will give the same oil flow on the eighth as on the first basic module.

The characteristics apply to supply oil flow of 130 l/min [34.3 US gal/min] with the actuation of one basic module. If several basic modules are activated at the same time, the characteristic depends on the load pressure of the actuated basic modules.

PVLP is set at an oil flow of 10 l/min [2.6 US gal/min].

The shock valve PVLP is designed to absorb shock effects. Consequently, it should not be used as a pressure relief valve.

If the working function requires the use of a pressure relief valve, a PVB basic module with built-in LSA/B pressure limiting valve should be used.

pressure drop a/b → t at max. spool travel within the proportional range (4.8 mm) [0.19 in).

Spools D and E have the same opening area for forward flow and return flow. Spool E can give 100 l/min [26.4 US gal/min] pressure compensated oil flow due to a higher pressure drop across spool E. This occurs during spool actuation only.

The wiring diagrams below and on page 56 to 59 show only the basic outlines for the electrical connection.

Voltage supplyFor a main transformer with stabilised output voltage, the ripple must not exceed 5% of rated voltage.

Signal leads must not act as supply leads at the same time unless the distance between the actuator module PVE and terminal board is less than 3 m [3.3 yards] and the lead cross-section is min. 0.75 mm2 [AWG 18].

buiLding in saFety

PVG 32 Proportional ValveTechnical InformationSystem safety

All makes and all types of directional control valves (incl. proportional valves) can fail. Thus the necessary protection against the serious consequences of function failure should always be built in.

For each application an assessment should be made of the consequences of pressure failure and uncontrolled or blocked movements.To determine the degree of protection that ought to be built into the system, Sauer-Danfoss makes the following distinctions.

1. Maximum safety demands2. High safety demands3. Average safety demands4. Limited safety demands.

58 520L0344 • Rev FE• Feb 2007

1.MaxiMuM saFety deMands


When the fault monitoring system in PVEH is connected, the reaction to electrical and mechanical faults (e.g. a spool seizure) is fast and operator-independent. See page 23 “fault monitoring”.

A system can be protected against many electrical, hydraulic and mechanical faults by building in components as shown in the diagram:R: Alarm logic EHA (or relay) connected to the fault monitoring system in PVEHE: Electrical emergency stopM: Solenoid valveC: Pilot-operated check valve

The alarm logic EHA cuts off current to the solenoid valve (M) when PVEH monitoring registers a fault. The solenoid valve then leads the oil flow direct from pump to tank. Thus all functions are without operating pressure, i.e. locked in position, because there is no pilot pressure on the pilot operated check valve (C).Actuation of the emergency switch (E) cuts off current to the proportional valve and the solenoid valve (M). Actuation in this case is manual, but the result is the same as above.Stopping or disconnecting the pump drive motor is another safety measure, if the system reaction time can be accepted.

Note: The neutral position switch in the remote control units should not be used. PVEH with fault monitoring must have a constant voltage supply.

59520L0344 • Rev FE • Feb 2007

2.high saFety deMands


The difference between this safety method and the one previously described (1) is that here there is no built-in automatic fault monitoring and a neutral position switch (N) is connected.The method still gives a high degree of protection, but requires operator intervention. It is recommended that the neutral position switch be always connected to the electrical system. This then automatically cuts off current to the proportional valve when the remote control unit is in neutral position.

60 520L0344 • Rev FE• Feb 2007

3.average saFety deMands


The difference from the previous method is that the LS- signal from the proportional valve is led direct to tank when the emergency switch (E) is actuated. This can be achieved by using the Sauer-Danfoss LS unloading valve PVPX, integrated in the pump side module.

In a system with open centre PVP and a fixed displacement pump, the effect of the PVPX is an almost pressureless system, 8-14 bar [120-200 psi] i.e. all functions requiring a higher operating pressure will not operate, see page 13.

The method can also be used in LS systems with a variable displacement pump and closed centre version proportional valve.The pressure after LS relief then depends on the pump stand-by pressure.

61520L0344 • Rev FE • Feb 2007

4.LiMited saFety deMands


The safety system can consist of an emergency switch (E) and a neutral position switch (N) if protection against electrical failure is the only requirement. Here, there is no protection against hydraulic and mechanical faults (spool seizured in an extreme position).

oiL

particLe content, degree oF contaMination

PVG 32 Proportional ValveTechnical InformationOther operating conditions

The main duty of the oil in a hydraulic system is to transfer energy; but it must also lubricate the moving parts in hydraulic components, protect them against corrosion, and transport dirt particles and heat out of the system. It is therefore important to choose the correct oil with the correct additives. This gives normal operation and long working life.

Mineral oilFor systems with PVG 32 valves Sauer-Danfoss recommends the use of mineral-based hydraulic oil containing additives: Type HLP (DIN 51524) or HM (ISO 6743/4).

Non-flammable fluidsPhosphate-esters (HFDR fluids) can be used without special precautions. However, dynamic seals must be replaced with FPM (Viton) seals. So please contact the Sauer-Danfoss Sales Organization if the PVG 32 valve is to be used with phosphate-esters.The following fluids should only be used according to agreement with the Sales Organization for Sauer-Danfoss:• Water-glycol mixtures (HFC fluids)• Water-oil emulsions (HFB fluids)• Oil-water emulsions (HFAE fluids)

Biodegradable oilsPVG 32 valves can be used in systems with rapeseed oil. The use of rapeseed oil is conditioned by- complying with the demands on viscosity, water content, temperature and filtering

etc. (see chapters below and technical data page 14).- adapting the operating conditions to the directions of the oil supplier.

Before using other biodegradable fluids, please consult the Sauer-Danfoss Organization.

Oil filtration must prevent particle content from exceeding an acceptable level, i.e. an acceptable degree of contamination.

Maximum contamination for PVG 32 is 23/19/16 (see ISO 4406. Calibration in accordance with the ACFTD method).

In our experience a degree of contamination of 23/19/16 can be maintained by using a filter fineness as described in the next section.

63520L0344 • Rev FE • Feb 2007

FiLtration

PVG 32 Proportional ValveTechnical InformationOther operating conditions

Effective filtration is the most important precondition in ensuring that a hydraulic system performs reliably and has a long working life. Filter manufacturers issue instructions and recommendations. It is advisable to follow them.

System filtersWhere demands on safety and reliability are very high a pressure filter with bypass and indicator is recommended. Experience shows that a 10 µm nominal filter (or finer) or a 20 µm absolute filter (or finer) is suitable.It is our experience that a return filter is adequate in a purely mechanically operated valve system.

The fineness of a pressure filter must be selected as described by the filter manufacturer so that a particle level of 23/19/16 is not exceeded.

The filter must be fitted with pressure gauge or dirt indicator to make it possible to check the condition of the filter.

In systems with differential cylinders or accumulators the return filter must be sized to suit the max. return oil flow. Pressure filters must be fitted to suit max. pump oil flow.

Internal filtersThe filters built into PVG 32 are not intended to filter the system but to protect important components against large particles. Such particles can appear in the system as a result of pump damage, hose fracture, use of quick-couplings, filter damage, starting up, contamination, etc.

The filter in the electrical actuator PVE protecting the solenoid valves has a mesh of 150 µm.

Bursting pressure drop for internal filters is 25 bar [360 psi].

PVG 32 Proportional ValveTechnical InformationOrder specification

An order form for Sauer-Danfoss PVG 32 hydraulic valve is shown on the next page. The form can be obtained from the Sauer-Danfoss Sales Organization.

Both the module selection chart on the previous pages and the order form are divided into fields 0, 1-10, 11, 12, 13, a, b, and c.

Each module has its own field:0: - Pump side module PVP - Plug for external pilot oil supply PVPC - Electrical LS unloading valve PVPX1-10: Basic valves PVB13: Main spool PVBS a: Mechanical actuator PVM (or PVE when option mounted)c: - Cover for mechanical actuation PVMD - Cover for hydraulic actuation PVH - Electrical actuators PVE (or PVM when option mounted)b: - Shock and suction valve PVLP - Suction valve PVLA 11: End plate PVS 12: Assembly kit PVAS

please state- Code numbers of all modules required- Required setting (P) for pump side module- Required setting of LSA/B pressure limiting valves, see pressure setting guidance below.

standard and option assemblyThe PVG 32 valve group is assembled the way the module selection chart shows if the code number for PVM is written in field a, and the code number for PVMD, PVE or PVH in field c.The valve group is assembled so that the mechanical actuator is mounted on the opposite end of the basic module, if the code number for PVM is written in field c of the order form and the code numbers for PVMD, PVE or PVH in field a.

reorderingThe space at the top right-hand corner of the form is for Sauer-Danfoss to fill in. The code number for the whole of the specified valve group (PVG No.) is entered here. In the event of a repeat order all you have to do is enter the number Sauer-Danfoss has given on the initial confirmation of order.

pressure setting limitsThe maximum setting pressure for the pressure limiting valves LSA or LSB depends on the chosen pressure setting for shock valve PVLP. The maximum values recommended to avoid interaction can be read in the following table.The figures in the table have been calculated according to the following expressions:- PVLP ≤150 bar: LSA/B ≤ 0.8 × PPVLP- PVLP >150 bar: PPVLP - LSA/B ≥ 30 bar.
